Marine,
You'll get lots of different opinions and advice here. Some will say "hunt the wind"...it's the only way. As important as it is to hunt the wind if you can, there are just times that you cant and that makes scent elimination very important.
You may already do some, most or all of this and are only concerned about the final touches...I'm not sure so here's my input.
Start by washing your clothes in scent free soap and/or baking soda and then store them in a scent free container. Personally, I put an old sock full of baking soda inside that container and use it to dust myself with once I get dressed in the field.
Shower with scent free soap/shampoo. Use scent free pit juice.
Don't put on your hunting clothes until you get to the field...if you can.
Finally, the question you really asked is about the scent spray and I use it every time I go into the field. Give yourself and your boots a light misting of the stuff and go for it. In the early season I also carry some scent free wipes to get rid of the sweat of walking to my stand. Wipe off with it and stick the used wipein a zip loc bag and you're good to go.
Oh yeah....Hunt the wind too...if you can.
Best of luck.
